• • Knowledge, Project, Public, Research, Teaching • , , , • 4 minutes of reading

Revised draft based on feedback provided following the Second Session of the UN-GGIM Committee of Experts on Global Geospatial Information Management January 2013 The use of geospatial information is increasing rapidly. There is a growing recognition amongst both governments and the private sector that an understanding of location and place is a vital component of effective decision-making. Citizens with no recognised expertise in geospatial information, and who are unlikely to even be familiar with the term, are also increasingly using and interacting with geospatial information; indeed in some cases, they are contributing to its collection – often in an involuntary […]

Location-Based Service (LBS)

• • Knowledge, Project, Public, Research, Teaching • , , • 2 minutes of reading

A Location-Based Service (LBS) is usually a service running on a mobile device that provides facts or recreational information. It employs geolocation to make the facts or entertainment more personal to the user of the application. An example of a typical LBS is one that identifies the location of a device and then discovers the location of restaurants in the immediate vicinity of that location. As LBS become more common, their commercial value will become more readily evident to corporations, who can use them to personalize users’ experiences with location-aware weather, coupons, and advertising. This is already becoming more common,

API (Application Programming Interface)

• • Knowledge, Public, Research, Teaching • , , • 2 minutes of reading

“What’s an API?” When a new programmer asks this question, they typically get the answer, “an application programming interface.” But APIs are so much more than their name suggests—and to understand and unleash their value, we must focus on the keyword interface. An API is the interface that a software program presents to other programs, to humans, and, in the case of web APIs, to the world via the internet. An API’s design belies much about the program behind it—business model, product features, the occasional bug. Although APIs are designed to work with other programs, they’re mostly intended to be

Definition of GIS

• • Knowledge, Public, Research, Teaching • , , • 1 minute of reading

GIS stands for Geographic Information Systems, but the “S” is increasingly being used to stand for science and studies as well. Geographic Information Science, and Geographic Information Studies are used increasingly. No universally agreed-upon definition has been put forth. Surprisingly, a number of GIS texts do not even attempt to define the term. Traditionally, GIS is a computer-based system for collecting, managing, analyzing, modeling, and presenting geographic data for a wide range of applications. Geographic Information Science, then, is the discipline that studies and uses a GIS as a tool. GIS is not simply creating maps with a computer. The

According to Dangermond, the top five trends in GIS technology today are as follows: Location as a service Advanced analytics Big data analytics Real-time GIS Mobility Dangermond continues: “The last leap in computing was the shift from the server to the cloud. Software as a service (SaaS) opened a world of opportunities for GIS, as shared map services like the World Imagery basemap are no longer separate from the unique services offered to users. GIS users can share data, collaborate, make mashup maps in the server, and then connect to the cloud. The next leap in GIS technology and computing

Database Modeling

• • Public, Research, Teaching • , , , , , • 1 minute of reading

Using abstraction from concepts by humans to their implementation in the machine, database modeling relies generally on a three-tier model: A conceptual model involving the identification of the geographic features to be included in the database as entities/objects, the definition of their attributes, and how they relate to one another. An abstraction and objective representation of the real world independent from the DBMS software to be used. A logical model, a resulting outcome from the transformation of the conceptual model using the DBMS data model techniques (e.g., relational, object, or object-relational). A physical model, a resulting outcome from the transformation of

Geocoding

• • Knowledge, Project, Public, Research, Teaching • , , , • 2 minutes of reading

Geocoding (geographically enabling unit records) is defined as the process of finding associated geographic coordinates (expressed in latitude and longitude) from other geographic data for the statistical units, such as street addresses or postal codes. (Geocoding is a way to ensure that the data “knows” where it is.) In other words, geocoding involves taking location information for these statistical units (such as address) and linking this information to a location coordinate (i.e., x,y,z coordinates) and/or a small geographic area. The geocodes (the location coordinates and geographic areas codes) obtained from this process can be stored directly on the statistical unit record

“A very common type of spatial analysis, and probably the one you are most familiar with, is optimization and finding the best of something. You might be looking for the best route to travel, the best path to ride a bicycle, the best corridor to build a pipeline, or the best location to site a new store. Using multiple input variables or a set of decision criteria for finding the best locations and paths can help you make more informed decisions using your spatial data.

Understanding Where

“If you don’t know where you are, you are lost. Understanding where is about putting the world in context. Where are you? What is around you? Very similar to when you were two years old, your journey of spatial analysis requires an understanding of how you fit into your geography. Understanding where includes geocoding your data, putting it on a map, and symbolizing it in ways that can help you visualize and understand your data. Within the taxonomy of spatial analysis, the first category of understanding where contains three types of questions. Types: • Understanding where things are (location maps)

“A blockchain is a growing list of records, called blocks, which are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. It is a ledger that records transactions in a verifiable, permanent way.” “Geography is critically important to capture in a blockchain record, which is why we are now calling this a geoblockchain.” “Adding location to the blockchain would provide enhanced security and validation because the same transaction cannot happen in two places at the same time. Use cases for blockchain being explored today include land title, supply chain, and data exchanges.

By Elysonia Alim and Shahabuddin Amerudin It is difficult to process GIS vector data when they are not aligned with one another. The need for different coordinate systems rose from the fact that some coordinate systems are better fitted to describe the geographical phenomenon occurring in a specific area. However, even commercial software had been proven to have questionable accuracy in coordinate system conversions. The purpose of this study is to develop a web application capable of converting the coordinate system of a GIS data format such as a shapefile for Peninsular Malaysia.
